Description

Enemies: K.L.J, J.A.R. AND R.A.T. Allies: C.A.R., FireLightin, Bloxxers, Invisible Killers, Ajarnie's clone army, army strong FIRST LEGOIN, F.E.A.R, c.r.a.b., The REAL Elemental Heroes. ========================================= Here is the official J.A.C. Shirt. All J.A.C. members must buy it. http://www.roblox.com/My/Item.aspx?ID=41453160 Thankyou! :) ========================================= We are a very friendly group. I happily accept most requests. Do not bribe other members or myself. If so you do it leads to direct exilement/expeltion. So don't do it. We are aiming to defeat the well known...(ask me for the answer). Rules: 1. Do not tell higher ranks than you what to do unless you have an extremely credible reason for it.

Membership history

Growth

Growth history is still building. We hold one measurement for this entry. A trend needs at least two, taken days apart — so this will fill in on its own rather than being estimated. We do not publish numbers we have not measured.
